Assume that a sample is used to estimate a population proportion p. Find the 95% confidence interval for a sample of size 238 with 172 successes. Enter your answer as a tri-linear inequality using decimals (not percents) accurate to three decimal places.

95% confidence interval for a Population proportion

0.6937 ≤ P ≤ 0.7515

Step-by-step explanation:

Explanation:-

Given sample size 'n' = 238

probability of successes  or sample proportion

95% confidence interval for a Population proportion is determined by

(0.7226 -  0.0289 , 0.7226 + 0.0289)

(0.6937 , 0.7515)

Conclusion:-

95% confidence interval for a Population proportion

0.6937 ≤ P ≤ 0.7515

50

step-by-step explanation:

-7/8

step-by-step explanation:

instead of subtracting you add the -6/8 and -1/8
